Feedback doesn’t just happen in robots and self-driving cars, but in the regulation of our very bodies and in the ways in which we transform raw ingredients into materials we can use, be they for Silicon chips, disease fighting monoclonal antibodies and vaccines, or even dinner. All of these processes – from regulating our blood sugar to making a stew – involve similar principles of feedback. The processes, although complicated in the details, can often be understood using some fairly simple and yet powerful models. We will talk about some of these.
Note: This wonderful introduction to feedback systems was presented by Professor Babatunde Ogunnaike of the University of Delaware. He gave me permission to to post his video online. A few months after this, he was diagnosed with a particularly aggressive cancer and passed away in early 2022. Tunde was an acclaimed leader in the field of chemical process control and the control of biological processes. He was also a beloved soul, a friend to all, and an amazing speaker and educator. Our hope is that posting this here will allow others to share in his wonderful legacy.
